From New York Times bestselling author CD Reiss comes a story of friendship, romance, and growing into a love that was always there.

Rachel knew exactly what turning thirty would be like. She had a plan, after all. First college, then a climb up the professional ladder. Love, marriage, children. All of it was on the schedule.

The cheap Hollywood apartment wasn't on the list. Neither was the string of heartbreaks. Or the effect her mother's cancer had on her career.

It's hard to stay practical and on point when everything takes a left turn.

Enter Sebastian, the nerd across the street. The boy she defended when he couldn't defend himself. The best friend she promised she'd marry if life didn't go according to plan.

Not only is he successful, confident, and gorgeous, but he also still has their handwritten marriage contract.

No one goes through with childhood wedding pacts.

That's crazy.

But their families might just be crazy enough to rent a hall and set a date. All Rachel and Sebastian have to do is fall in love.
